General description

Protopine is a celandine alkaloid and a bioactive compound associated with the plant families including fumariaceae, berberidaceae and papaveraceae. It is metabolized by demethylenation in the presence of the cytochrome enzymes cytochrome P450 family 2 subfamily d polypeptide 1 (CYP2D1) and cytochrome P450 family 2 subfamily c polypeptide 11 (CYP2C11).

Application

Protopine hydrochloride may be used in the calibration curve preparation for the quantification of alkaloids from Fumaria capreolata using liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry (LC-DAD-MS) and tandem mass spectrometry(MS/MS). It may also be used as an alkaloid in cytotoxicity and permeability studies carcinogenic cell lines.

Biochem/physiol Actions

Protopine possesses anti-parasitic, antimicrobial and anti-inflammatory property. It mediates mitotic arrest by favoring tubulin polymerization. Protopine elicits anti-invasive effects in breast cancer tumor progression.. It also provides protection against oxidative stress-induced cell death.
Protopine hydrochloride is a Ca2+ channel blocker and antiplatelet agent.

Caution

Protect from light.

With the application of near-infrared spectroscopy (NIRS), a convenient and rapid method for determination of alkaloids in Corydalis Tuber extract and classification for samples from different locations have been developed. Five different samples were collected according to their geographical origin

S-Adenosyl-l-methionine:tetrahydroprotoberberine cis-N-methyltransferase (EC 2.1.1.122) catalyzes the conversion of (S)-stylopine to the quaternary ammonium alkaloid, (S)-cis-N-methylstylopine, as a key step in the biosynthesis of protopine and benzophenanthridine alkaloids in plants. A full-length cDNA encoding a protein exhibiting 45 and 48% amino

Identification of putative biomarker molecules within the genus Corydalis (Papaveraceae) was pursued by combining conventional off-line sample enrichment with high-performance liquid chromatography-solid phase extraction-nuclear magnetic resonance (HPLC-SPE-NMR) based structure elucidation. Off-line reversed phase solid phase extraction (SPE) was used to

A sensitive and specific liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) method has been developed and validated for the simultaneous quantification of tetrahydropalmatine, protopine and palmatine in rat plasma using phenacetin as the internal standard (IS). Two hundred microliters plasma samples were
